The Electro-Harmonix Small Stone is a legendary analog phaser that has influenced generations of musicians. Its rich, swirling modulation adds depth and movement to both clean and overdriven sounds. With just one Rate knob and a Color switch, you get everything from slow, smooth sweeps to fast, resonant phasing. The all-analog circuitry delivers a warm, natural tone reminiscent of the seventies. A compact classic that still sets the standard for musical phasing.
